Review

The Corsair RM750E is a notable addition to the power supply market, primarily catering to gaming enthusiasts and mainstream users who require a reliable and efficient power source. Building on Corsair's commitment to delivering high-quality components, the RM750E integrates several features that make it a formidable choice for a wide range of builds.

Design and Build Quality

The Corsair RM750E sports an aesthetically pleasing design, featuring a smooth satin black finish complemented by geometric design elements and chamfered edges. Measuring a standard ATX length of 140 mm, its form factor ensures compatibility with most tower PC cases, although it does limit the cooling fan size to 120 mm. The modular design allows for neat cable management, with an all-black cable aesthetic, enhancing the internal appearance of computer builds (AnandTech).

Performance and Efficiency

At the heart of the RM750E's strengths is its 80 Plus Gold efficiency rating. It achieves a notable efficiency of up to 92.4% at 230 VAC during cold testing, maintaining a reliable performance under different load conditions. This efficiency, however, dips slightly during hot testing, dropping to around 90.1% at high temperatures. Such performance indicates that while it is robust in cooler settings, those planning to operate it in warmer environments should account for this drop in efficiency (AnandTech).

The unit excels in electrical performance, with superb voltage regulation. Specifically, it delivers a regulation of 1.1% on its 12V rail, displaying excellent ripple suppression across its outputs. This makes the Corsair RM750E a dependable choice for systems needing stable and clean power delivery. Additionally, all critical protection features necessary, such as Over Current Protection (OCP) and Short Circuit Protection (SCP), are thoroughly implemented, ensuring the power supply remains protected under various conditions (TechPowerUp).

Features and Connectivity

• Fully modular design for easier cable management.
• 750W capacity, enough for most gaming and enthusiast systems.
• Support for ATX 3.0 standards, bringing in a 12V-2x6 connector capable of handling PCIe 5.0 devices.
• Includes a quiet Hong Hua 120 mm fan, optimized for low-noise operation under medium loads (Tom's Hardware).

Market Position and Value

Priced affordably at $99.99, the Corsair RM750E offers excellent value given its feature set and reliable performance standards. However, potential buyers may want to consider its competition, such as the RM750x, which offers slightly better components at a marginally higher price. Notwithstanding, the RM750E’s 5K+ monthly sales figure speaks to its popularity and acceptance in the market, showing it is a power supply that meets the expectations of many users seeking efficiency without breaking the bank (AnandTech).

Conclusion

The Corsair RM750E emerges as a power supply unit that balances performance, efficiency, and cost-effectiveness. While it may have minor drawbacks, such as susceptibility to thermal conditions, these are mitigated by its excellent voltage regulation, modular design, and an appealing price tag. Therefore, for those embarking on a build or seeking to upgrade their power supply, the RM750E promises a commendable power solution that withstands the challenges of modern gaming and computing requirements.
